Specification of Letters Patent.

Serial No. 431,346.

To all whom it may concern:

Be it known that I, JOHN J. DIPPEL, a citizen of the United. States, residing at Evansville, in the county of Vanderburg and State of Indiana, have invented certain new and useful Improvements in Draft-Rigging, of which the following is a specification.

My invention. relates to improvements in draft riggings, and has for one of its objects the provision of a very simple, strong and durable device of this character so con.- structed as to be readily adapted to cars of different makes, such as freight cars, furniture cars, passenger coaches and the like.

Another object of the invention is the provision of a railway draft apparatus which may be readily applied to or detached from the car, which will strengthen the under frame of the car and which will cushion both the push and the pull exerted upon the car, thus serving as a buffer as well.

With the above and other objects in view, my inventionconsists essentially of a draft bar carrying a coupler, springs for cushioning the longitudinal movements of the draft bar, and means for attaching the draft bar to the frame of a car.

The invention further consists of railway draft apparatus embodying certain other novel features of construction, combination and arrangement of parts substantially as disclosed herein and as illustrated in the accompanying drawings, in which:

Figure 1, is a broken side elevation of a portion of a car frame with my invention applied thereto, the car being one of that type which is provided with longitudinal draft sills running the length of the car. Fig. 2, is a longitudinal sectional view of the invention. Fig. 3, is a plan view of the invention as applied to a car having a pair of longitudinal draft sills, the invention being placed between said sills. Fig. 4, is a view of the invention showing the casing as equipped With flanges for attachment to the under frame of a car.

Referring to the drawings and more particularly to Fig. 1 the numeral 1, designates the draft sill, 2, the draft timber applied thereto, 3, the transom, 4, the end sill, and 5, the deadwood of an ordinary car frame. The invention itself comprises a boxing or casing 5*, 5 through which the draw bar 6, passes, the draw bar having a coupler head 7, on its outer end, and a nut or other adjustable fastening 8, on its inner end. The draw bar passes through a pair of spaced. partitions 9, in the casing which form bearing surfaces for the springs 10, and 11, which encircle the draw bar, the first named being a draft spring and the other being a buffer spring. The nut on the end of the draw bar and the washer 12, serve to confine the draft spring against the inner partition, and the shoulder 13, on the draw bar, serves as an abutment for the buffer spring. A plate 14, is bolted or otherwise secured to the inner end of the spring casing and this plate is provided with a pair of ribs or lugs 15, which engage over the transom of the frame, the bolt 16, passing through the transom and plate to hold the parts together.

For securing the attachment in place, the top of the casing is usually provided with the three pairs of upstanding attaching lugs or ears 17, located at the ends and middle portion of the casing as shown in Figs. 1 and 2, which ears engage the sides of the draft sill, and bolts 18, are passed therethrough, thus securely fastening the draft rigging to the under frame and at the same time strengthening the draft sill. The transom plate serves to distribute the strain throughout the frame.

The tension of the springs is adjusted by means of the nut on the inner end of the draw bar, and openings 19, are formed in the easing to admit a tool for performing this ad justment.

When the invention is to be applied to a car equipped with a pair of spaced longitudinal draft sills as illustrated in Fig. 3, the easing is placed between the sills with the end of the casing bearing against the end. sill and the transom plate secured to the transom. In this construction, the securing bolts would be passed through the draft sills and easing as at 20, or as shown in Fig. 4, the casing might be made with flanged edges 21, through which the securing bolts could be passed.

From the foregoing description taken in connection with the drawings, it will be obvious that I have produced a practical and efficient railway draft appliance and one which. accomplishes all the objects aimed at.

I claim:

1. In a draft rigging, the combination with the draft timbers of the car, of a casing secured to said timbers and formed with a pair of spaced partitions with openings for the passage of the draw-bar, a coupling head, a draw-bar passed through the openings in said partitions, springs around the drew-her upon opposite sides oi said partitions, and means on the inner end of the dram-her hearing against one of said springs for adjusting the tension thereof,
